To all whom t may concern:

Be it known that we, ALBERT D. GROVEF. and EARL E. BARBER, citizens of the United States, and residents, respectively, of Malden, in the county of Middlesex, State of Massachusetts, and Boston, county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Coin-Testing Mechanisms for Coin- Controlled Vending-Machines, of which the following is a specification.

Our invention relates to coin-controlled vending machines and has for its object the provision of mechanism for automatically testing the deposited coins in several particulars.

One function of our coin-testing mechanism is to prevent iron slugs from operating the machine. Another function yis to arrest the passage of rings or washers into operative position withinI the machine, and the third function of the mechanism is to test the deposited check as to thickness.

The coin-testing mechanism of our invention is so compact in arrangement of parts as to occupy but very little space, so that our invention is particularly applicable to vending machines used in theaters. As is well known, these theater vending machines must be of the smallest possible dimensions, so as not to constitute an obstruction when fastened to the back of the theater chairs. As far as we are aware, machines of this type have heretofore not been protected by coin-testing mechanisms having one or more of the functions above referred to, for the reason that the coin-testing mechanisms of the prior art are too elaborate in their construction and operation to admit of application to a vending machine of essentially small dimensions-such as a theater machine. As a result, the 'operation of these machines'has in many instances been rendered unprofitable, and in some cases they have been operated -at a loss, due principally to the use of iron slugs, which opened the machine as readily as a genuine coin.

.Therforegoing diiculties are entirely obviated by the use of our new coin-testing mechanism which automatically locks the machine against operation through other a coin-controlled locking member and a' magnetically controlled device for automatically locking said member against operation when a check of magnetic material is deposited. rlhe precise function of this locking member is immaterial as far as the basic principle of our invention is concerned. ln the illustration shown in the drawings, this locking member controls the slide or bolt which locks the lid of the machine. l

Viewed in another aspect, the magnetic feature of our invention comprises broadly a movable coin-carrier for conveying the deposited coin into operative position, and means for automatically locking the carrier against complete operative movement, when a check of magnetic material is deposited. The carrier is readily operable to initial position to carry the spurious check back to the coin-opening whence it may be withdrawn by hand.

Another feature of our invention consists in positively arresting the operation of the coin-carrier when a ring or washer is deposited. This is accomplished by means of a yieldably mounted pawl which is projected into the opening of the ring or Washer on the carrier and thereby acts as a stop against further movement of the same. The coin-carrier is so constructed that when it comes into engagement with the pawl it automatically represses the same, and is not therefore interfered with when operated in either direction without a coin. Vhen a coin is in the carrier the pawl is held back in its inoperative position by boththe carrier and the coin, and the machine operates as though the vwashercatching pawl were not present. This free v operation of ythe coin-carrier in either direction when empty or when carrying a good coin is an important feature of our invention.

Another object of ourl invention consists in providing means for testing the coin as to thickness. This is accomplished by a recess or cutaway portion in the projection of the locking member which extends into the path of the coin on the carrier. Unless the coin be of the requisite thickness, it will enter the recess on the projection of the locking member without operating the same.

While the purpose of our invention may be mechanically carried out in various ways,

we have shown in the accompanying drawings a machine provided with our new cointesting mechanism in the form now best known to us.

In these drawings Figure 1, is a front view of the machine with parts broken away for greater clearness. Fig. 2, is a rear view of the casing carrying the coin-operated lock and the coin-testing mechanismof the machine, certain parts being broken laway for the sake of clearness. Fig. 3, is a plan view of the machine with one of vthe lids in open position. Fig. 4, is a vertical section through the casing of the machine on line 4 4 of Fig. l. Fig. 5, is a vertical section on line 5 5 of Fig. 1. Fig. 6, is a vertical section through the front or supplemental casing of the machine'which carries the coin-controlled and coin-testing mechanisms. Fig. 47, is a horizontal view in cross-section on line 7 7 of Fig. 2. Fig. 8, is a detached face view of my new coincarrier. Fig. 9, is an edge view of the same; and Fig. 10, is a fragmentary view in transverse cross-section on line 10 10 of Fig. 2.

To the front walll of the main casing A, which may be of any suitable construction, is attached the supplemental casing B which carries the coin-controlled lock of the machine aswell as the coin-testing mechanism of our invention. In the specific instance shown vfor the sake of illustration, the main casing A is divided by a central partition 1 into two.compartments,indicate'd by 2 and 3. These compartments are provided with lids or covers 4 and 5, respectively, which are hinged at the top of the main casing by means of a rod 6. When in closed position, the lids are flush with the top of the casing. At their under side the lids are provided with a spaced flange 7 having a slot 8 therein for cooperation with a locking member, as will be presently explained.

The supplemental casing B is very shallow as compared with the main casing, and therefore adds but little Width to the machine when attached in place. This supplemental casing comprises a casting 9, a

back plate 10 and a front or cover plate 11. Between the plate 10 and the front wall of the main casing A is interposed a spacing plate 12 for accommodating certain parts, as hereinafter explained. The supplemental casing B is secured to the main casing by bolts or screws 13 passing through openings 14 into the main casing. Preferably, the front wall of the main casing is provided with a reinforcing plate 15 for receiving the fastening devices.

The casting 9 is at the back formed with a recess or cutaway portion forming the two coin-entrance slots 15 and 16, a central chamber 17, and a common coin-exit slot 18 open at the bottom. In the chamber 17 operates the rotatable coin-carrier 19 which is in the form of a disk having a pair of oppositely arranged coin-receiving portions 20, as best shown in Fig. 8. The coin-ear rier 19 is operatively connected with the knob or wheel 21 at the front of the machine in any suitable manner. In the drawings I have shown the coin-carrier provided with a rectangular slot 22 into which passes the rear end of the stub shaft 23 extending from the knob 21. A screw 24 or other fastening device secures the coin-carrier to the stub shaft 23. By simply removing the screw 24, the coin-carrier and the knob may be readily separated. The stub shaft 23 passes through an opening in the hub or bearing portion 25 formed in the main plate of the casting 9, as best shown in Figs. 5 and 7.

On a stud 26 arranged centrally on the rear side of the casting 9 is pivoted a lever 27 provided at its lower end with a forwardly extending lug 28 which lies in the plane of operation of tl .e coin-carrier, as best shown in Fig. 5. The lug 28 passes through an arc-shaped opening or slot 29 in the rear plate 10. The upper end of the lever 27 is arranged to operate between a pair of lid-locking slides or boltsl 30 and 31, which are slidably mounted on the plate 10 by means of pins or studs 32 engaging in theslots 33 formed in the slides. This is best shown in Fig. 2. Each of the lid-locking slides is provided with a rearwardly extending lug 34 and forwardly extending lug 35. The lever 27 and the slides 30 and 31 operate in the opening or chamber 36 formed in the intermediate spacing plate 12. The rearwardly extending lugs 34 extend through alined openings in the front wall of the main casing and the reinforcing plate 15 into engagement with the flanges 7 on the lids 4 and 5, as clearly shown in Fig. 4. When the slides 30 and 31 are in their normal or unoperated position, the lug 34 of each slide engages the flange 7 of the associated lid and holds the same locked. In Fig. 2 the slide 30 is shown in normal position. However, when one or the other of l the chamber or recess the slides is operated into releasing position, as will presently be explained, the lug 34 comes into alinement with the slot 8 in the flange 7 of the lid, and thereby causes the same to be thrown open by the springpressed package in the magazine; Fig. 2 shows the slide 31 in operated or releasing position.

With each of the locking slides 30 and 31, is associated a locking member 37 and 38, respectively, which is slidably mounted in 17 of the casting 9. Fach of these locking members is at its upper end provided with a rearwardly extending lug 39, which extends through a vertical slot 40 in the plate 10 into engagement with the projection 41 of the associated slide when the locking member is in normal or uppermost position. The locking members 37 and 38 are normally held in uppermost or.

locking position by springs 42, which bear at their upper end against the top of the slots 43 formed in the locking members, and at their lower ends against the lugs 44 projecting rearwardly from the casting 9. It should be noted that the locking members 37 and 38 are arranged in the plane of operation of the coin-carrier', and therefore in the plane of movement of the coin on the carrier.

The projection 45 of each locking member has a beveled coin-engaging surface 46.l

The operation of the coin-controlled locking mechanism as thus far described will now be understood lows: Let us say that the purchaser desires the package of goods in compartment 2,

which is the left-hand compartment. He deposits the required coinas a nickel-into the coin-slot 16, and turns the knob 21 to the left. No matter in what position the coin-carrier may be when the coin is deposited, rotation of the carrier will bring one of the coin recesses 2O into position to receive the deposited coin, which is held in operative position betweerrthe coin-carrier and curved wall 47 of the coin-slot. As the coincarrier is rotated, the deposited coin is carried along the wall 47 until it strikes the coin-engagin surface 46 of the projection 45 Aon the Tocking member 38. Further movement of the coin-carrier causes the coin to depress the locking member into releasing position, as shown in Fig. 2, where the coin is indicated at C. The rst eect of the coin, therefore, is to draw the locking lug 39 of the member 38 out of engagement with the lid-locking slide 31. Continued rotation of the coin-carrier brings the coin into engagement with the lug 28 at the lower end of the operating lever 27 and rocks the uper end of the lever against the slide 31, which is thereby shifted into releasing posi- Fachof the locking members has alateral extension 45 arranged to project into. the path of movement of the deposited coin.-

and may be stated as fol-y ing position.

thrusts the package upwardly and thereby opens the lid. This being a common expedient, it has not been thought necessary to show it. Should the purchaser desire a package from theV right hand compartment, he deposits the coin in the slot 15, and turns the knob toward the right. This causes the coin to unlock and operate the slide 30 in` the manner above described.

A fter the coin Chas actuated the lever 27, further movement of the coin-carrier forces the coin froml between the lug 28 and the projection 45 of the associated locking member, and allows the same -to drop into the coin-exit slot 18, where it is retained by the bar or bolt 48, to release the coin. The bolt 48 is withdrawn by means of a key inserted in the slot 49 formed in one side vof the casting 9. This key is adapted to actuate the tumblers 50 of the lock 51. As the lock 51 forms no part of our present invention, we have not deemed it necessary to show or describe any specific form of lock and key for withdrawing the bolt 48.

. As previously stated, Y the lid-locking slides 30 and 31 are at their adjacent upper ends provided each with a forwardly extending lug 35, which projects through the horizontal slot 52 in the plate 10. The arrangement of thelugs 35 is such that when a slide is in normal or locking position, its lug 35 'does not interfere with the passage of the coin through the associated coin slot. This is clearly shown at the left of Fig. 2. However, when the slide is in actuated or releasing position, its lug 35 projects into the associated coin-slot, so as to positively prevent the insertion of a coin into that slot. In Fig. 2, the lug 35 of the slide 31 is shown in `slotclosing position. It will thus be seen that when a compartment is empty no coin can be inserted into the corresponding coin-slot, whereby a careless customer is prevented from losing his coin. Theslides. 30 and 31 are passive-that is to say they are not spring-controlled and remain in their operated position. Tt therefore becomes necessary to restore them to their initial or lockspecial key adapted to be inserted into the key-slots 53 formed in the sides of the casting 9 near the upper end thereof. One of This is done by meansof a these slots 1s shown at the left of Fig. 2.

The other slot is concealed by the plate 10. Each of the slides 30.and 31 is at its outer edge provided with a forwardly extending lug 54 which projects through the horizontal l slot 55 in the plate 10, as clearly shown at the right of Fig. 2. The lugs 54 extend into the key slots 53, sothat the inserted key engages the lugs and forces the slides inwardly into normal position.

en, during the rotation of the coincarrier, the coin is forced out of engagement with the associated locking member 37 or 38 after the corresponding slide has been moved into releasing position, said member is at once carried upwardly by the spring 42, so that the locking lug 39 engages the inner shoulder 41a of the extension 41 of the slide. This locks the slide against return movement and consequently prevents relocking of the empty compartment by an unauthorized person. It is therefore necessary, before the actuated slides can be restored, to depress the loclng members 37 and 38 out of engagement with the extensions 41. This is done by means of the bars 56 which are slidably arranged in the recesses 57 exten ng downwardly from the key slots 49. Each of the bars 56 is at its lower end provided with an inwardly extending lug 58 adapted to engage the lateral lug 59 on the associated locking member 37 or 38. Only one of the bars 56 is shown entirely in Fig.. 2. The bar at the right is partly concealed by the plate 10. Normally, the bars 56 rest by gravity at the bottom of the recess 57 as shown at the right of Fig. 2. When the locking member 37 or 38-is moved into elevated position, as shown at the left of Fig. 2, the lug 59 carries the associated bar 56 upwardly, so that the beveled outer end 60 of the bar 56 extends into the key slot 53. When, therefore, the key is inserted into this slot, the bar -56 is rst depressed to move the associated locking member into releasing position, and as the key is pushed inwardly it comes into contact with the lug 54 of the lid-locking slide and forces the same inwardly into normal position. It is, of course, understood that this restoring of the slides 30 and 31 does not take place until after the attendant has replenished the machine, and while he holds the lids down inclosed position.

The foregoing construction of coin-operated lock does not in and of itself constitute a part ofyour invention, as that construction is the subject matter of the pending application, Serial No. 718,220, filed September 3, 1912 by Samuel J. Kelly and John A. Webster as their joint invention.

W'e have illustrated our invention 'asapplied to a coin-controlled lock of the foregoing construction merely for the sake of illustration, and not by Way of limitation of our invention.

In applying our invention to the coincontrolled lock as above set forth, the object is to prevent the operation ofthe members 37 and 38 into releasing position, when a ,69 and the lock have beveled the engaging surfaces `of the check of magnetic material, or a washer, or a check of less than the prescribed diameter or thickness, is deposited in the machine.

We will now take up in detail these different functions of our new coin-testing mechanism. In the recess or chamber 61 at the front of the casting 9, is pivoted a pair of supports 62 and 63 on studs or pins 64.

hese supports carry the magnets 65 and 66, respectively. These magnets are rigidly mounted on their supports in any suitable manner-as by means of lugs 67 struck up from the supports which are preferably constructed of sheet metal. The poles of the magnets project through openings 68 in the casting 9. These openings are sufficiently large topermit movement of the magnets, as hereinafter described. The outer or free ends of the poles of the magnets lie substantially Hush with the inner wall of the charnber 17 through which the coin is conveyed by the coin-carrier. Fig. 7, shows clearly the termination of the magnet poles in line with the inner wall of the recess 17. By virtue of this arrangement, the deposited check is moved past the poles of one or the other magnet, and comes substantially in contact therewith. Each of the magnet supports 62 and 63 is at its lower end provided with a rearwardly extending lug 69, which projects through the opening 7 0 in the casting 9 into the path of movement of the associated locking member 37 or 38. Each of these members is at its lower end provided with a slot a, adapted to receive the lug 69 when the latter is inoperated position, and thereby lock the said member against downward movement into releasing positi'on.

The operation of the magnetic tester of our new coin-testing mechanism is as follows: YLet us say that an iron slug is deposited in the coin-slot 15 and the coin-carrier turned `counter-clock-wise (as viewed in Fig.

As soon as the slug comes opposite the netic attraction causes the magnet to adhere to the slug, and as the latter is swung t0- ward the left (as viewed in Fig. 2) by the coin-carrier, the magnet and the support on which it is mounted are also swung slightly to the left, with the result that the locking lug 69 at the lower end of the support 63 is brought into alinement with the slot 7 0a on the locking member 37. This movement of the lug 69 into locking position takes place before the slug has forced the member 37 past the lug 69. To prevent any possible failure of this interlocking between the lugs ing members 37 and 38, we

lugs 69 and the locking members, shown in Fig.. 2, movement of the members 37 and 38 as clearly so that only a very slight locking lugs toward the is required to enable the nieuwe oppositely beveled edges of the locking members to cam lugs 69 into the slots 70a. By this arrangement the interlocking of the lugs 69 with 'the members 37- and 38 is rendered certain, no matter how quickly the slug may be carried past the magnets. The slight downward movement of the locking members before they are locked by the lugs 69 is not sufficient to cause unlocking of the slides 30 and 31. The engagement of the lugs 69 with the locking members 37 and 38 positively prevents further operation of the coin-carrier, but it does not interfere with the return movement of the carrier to bring the slug back into the coin-entrance opening for removal by hand. This free operation of the coin-carrier in the reverse direction is essential, otherwise the machine would become clogged after the insertion of the first slug. The casting9 is preferably recessed opposite each coin-slot, as shown in Figs. 1 and 3, to allow the slug to be more readily grasped by the fingers. The supports 62 and 63 hang by gravity in such a position that the lugs 69 are out of the path of movement of the members 37 and 38, as clearly shown in Fig. proper coin is deposited, the operation of the members 37 and 38 into releasing position is not interfered with by the lugs 69.

Tn order to insure the proper operation or the magnets, we prefer to employ means for forcing the deposited check against the magnetic poles. 1n the drawings,` we have shown a spring blade 72 associated with each pair ofmagnet poles, and so arranged as to project into the recess 17. These spring blades may conveniently be cut out of the plate 10. The upper ends of the spring blades 72 are beveled so that the deposited check may be forced past them. These springs yieldingly press the coin or check against the inner wall of the recess 17, and therefore against the poles of the magnets. 1n this way there is no chance of any air gap between the magnet poles and the iron slugs, which would weaken the attractive force of the magnet and render its operation uncertain.

Tt will be seen from the foregoing that we have provided an exceedingly simple and efficient means for automaticallydlocking the coin-controlled mechanism against operation when a magnetic slug is deposited in the machine. 0f course, it should be understood that the precise arrangement of magnets as herein shown, has been selected merely for the purpose of illustrating our invention, which is applicable by those skilled in the art to coin-controlled mechanisms of various construction@ l We will now describe the means for automatically locking ythe coin-carrier against full operative movement when a check with 95 an opening-such as a washer or ring--is 2.` Consequently, when a vin Figs. 1 and 8),

mwa @mi deposited. The casting 9 is on the front side provided with a pair of lugs 73 which serve to pivotally support the pawls 74 and 75. The upper free ends 76 of these pawls project rearwardly through slots 77 in the casting 9. A spring blade 78 is secured at an intermediate point to the casting in any suitable manner, as by a screw 7 9l `(see-Fig. 5), and is adapted to bear at its ends against the pawls 74 and 75 to force the saine rearwardly. llt will be observed that the pawl 74 is nearer to the axis of rotation of the coin-carrier than the pawl 75. The reason for this is to allow free rotation of the coincarrier in either direction by repressing the pawls through the medium of oppositely arranged inclined surfaces on the front face of the coin-carrier.` These inclined surfaces are best shown in Figs. 8 and 9. There are two sets of these surfaces-an outer set numbered 80, 81, 82, and 83, and an inner set numbered 84, 85, 86, and 87. The outer set of inclined surfaces is adapted to engage the outer pawl 75, while the inner surfaces are arranged to engage the inner pawl 74. The diametrically oppos'te outer surfaces 80 and 82, and the diametrically opposite inner surfaces 85 and 87, are beveled outwardly from the edge of the coin-carrier. This is indicated by the shading in Fig. 8, and by the dotted lines representing surface 87 in Fig. 9. The diametrically opposite outer surfaces 81 and 83, and the diametrically opposite inner surfaces 84 and 86, incline outwardly from the coin-carrier and terminate each in a lug 88. lit will be noted that the two sets of inclined surfaces are beveledreversely with respect to each other, whereby the inner set of surfaces serve to repress the pawl 74 when the coin-carrier is rotated in one direction, while the outer'set of surfaces represses the pawl 7 5 when the coin-carrier is rotated in the opposite direction. We can perhaps best folj vlow the action of the inclined surfaces on their respective pawls by reference to Fig. 8. 1f we imagine the coin-carrier rotated coun terclockwise, it will be clear that the outer set of surfaces approaches the outer pawl7 5 from below-that is to say, in the direction of the beveled under-surface 89 on the head of the pawl. rTherefore, the projections 88 of the surfaces 81 and 83 repress the pawl 75 forwardly. The inner inclined surfaces 85 and 87 approach the pawl 74 head-on, and cause it to ride over the same. When the direction of rotation of the coin-carrier is reversed, (that is to say, clockwise as viewed the inner set of surfaces approaches the pawl 74 from below, so that the inner projections 88 force this pawl out application Ser. No. 1915.

do not interferewith the rotation of the coin-carrier in either direction, whether it is empty or whether` it carries a coin. However, when the deposited check is a washer or a ring, one or the other of the two pawls will snap into the opening of the washer or ring as soon as the same comes into alinement with thehead of the pawl, whereby further rotation of the coin-carrier is prevented. The preliminary movement of the coin-carrier before itis thus locked by the pawl, is not suicient to move the locking member 37 or 38 into releasing position. Furthermore, when the pawl interlocks with the washer, the position of the washer is such that the coin-carrier is free to be rotated'in the reverse direction to carrythe washer back into the coin-slot and project `the same out of the slot siiiciently to permit its removal by hand.A If the machine has only one goods compartment, it is of course obvious that only one Washer-catching pawl? .is required, in which event the coin-carrier need have but one set of inclined surfaces.

It will be seen that our new form of washer-testing struction and pawls are housed within the recess or chamber 61, their presence does not add to the dimensions of the machine.

To prevent the locking members 37 and 38 from being operated by a thin disk, we provide a recess or cutaway portion 90 on the front side of the extension. The springs 72 will force the check in the direction of the recesses 90, so that should the check be of less thickness than the width of the recess 90, it will pass through said recess without actuating the associated locking member 37 Owing to an oiiicial requirement for division, the washer-catching feature of our i11- vention has been divided out of -this case and forms the subject-matter of a separate Having thus described our invention what we claim as new and desire to secure by Letters Patent of the United States is:
